An optical capillary rheometer has been fabricated with capillary diameter ranged from 50μm to 200μm.On the rheometer extremely low shear rates(1~5 s^-1) for polyacrylamide soltion can be recorded.The results showed that at extremely low shear rates PAM solution behaves as a Bingham solution and the concentration and temperature show great effects on the non-Newtonian index, consistency coefficient, yield shear stress and apparent viscosity of the PAM solution.
